Claude Code: ask. ### `youtube_comment_reply` - The name "youtube_comment_reply" says "comment": a word for a change. - The name "youtube_comment_reply" also says "reply": a word for sending, and what is sent cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Responde comentários como o canal conectado. Aceita VÁRIAS respostas numa chamada (`replies`), e um item que falha não derruba os outros. `parent_id` tem que ser o id de um comentário de TOPO (campo `id` do thread devolvido por youtube_comment_threads), nunca o id de uma resposta. Cada resposta consome 50 unidades da cota da API do YouTube, então responda o que importa em vez de varrer o canal. ``` ## Changes things (28) Creates or changes something that can be changed back. Claude Code: ask. ### `authenticate` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header `Authorization: Bearer ` for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "" } after the user pastes, or with no args to get the link. ``` ### `marketplace` - Nothing in its name or description says what it does, so it is counted as a write. - Findings: info credentials-mention Description, as the server wrote it: ```untrusted-server-text The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/ link that opens without login. ``` ### `report_bug` - Nothing in its name or description says what it does, so it is counted as a write.
